UNITED GEORGE L. OLSEN, OF SALINAS,'OALIFORNIA- BEET LIFTER.

Application filed October 2, 1924. Serial No. 741,246.

- T all whom it may cancer-n:

Be it known that I, GnononL. OLsnN, a citizen of the United States, and a resldent of Salinas, in the county of Monterey' and State of California, have invented certain new and useful Improvements in Beet Lifters, of which the following is a specification. Y

It is one object of the present invention to provide a device of the character indicated that may be readily assembled and adjusted in a plurality of units for simultaneously lifting the beets in two or more rows.

It is another object of the invention to provide a device of the character indicated in which the angle of the several lifting blades relative to the normal ground surface may be uniformly altered as desired.

It is another object to provide a device in which the lifting blades of each pair may be readily spaced as desired and in which the several pairs may be readily spaced as desired.

It is still another object to provide a structure that may be carried upon a framework built therefor or, if so desired, mounted upon the frame of a cultivator or other earth working implement.

Finally, it is an object to provide a structure of the character indicated that is simple in construction, economical to manufacture, and highly efficient in its practical application.

In the drawing Figure 1 is a plan view of the device mounted upon a cultivator framework, part broken away. i V

Figure 2 is a section on 22 of Figure 1.

Figure 3 is a section on line 33 of Figure 1.

Referring more particularly to the drawing, I show at 1-1 a portion of two parallel bars of a cultivator frame, and 2 a cross 45 beam mounted thereon.

At 3 and 4 I show a pair of parallelly arranged bars spaced a distance apart both laterally and vertically as clearly shown in Figure 2, and rigidly held in these positions 50 by bars 5 through the medium of flanged elements 6 bolted thereto and to the said bars 5 as at 7. v

Each bar 5 is pivotally mounted upon the rear end of one of the bars 1 in any suitable manner as by a bolt 8, and is provided with a head portion 9 having a vertically extending slot 10 formed therein.

A bolt 11 is set in bar 1 and passes through slot 10 so that the said bar 5 may have a vertical pivotal adjustment, it being held in the desired position by tightening up the bolt 11.

These parallel bars 3 and 4 form the sup port and guide for the several lifter blades 12 through the medium of standards 13.

Each standard 13 assumes a vertical position at its upper end and passes between the parallel bars 3 and 4 to which it is securely and rigidly fastened by means of suitable collars 14 fitted with set screws 15 and slidably mounted on bars 3 and 4 as shown at 16 and 17 and secured in any desired position thereon by set screws 18.

Since the several lifting blades are rigidly mounted on the pivotal bars 3 and 4 it is obvious that by shifting their position about pivotal point 8 the angle of all the lifting blades is altered in like degree. To further strengthen the structure, I provide a rod 19 connected to cross beam 2 in a vertical plane passing midway between the two center blades of each two adjoining pairs of lifting blades as shown at 20. This rod is forked at 21 and connected to the standards of the, two center blades as at 22-23, and is fitted with a turnbuckle 24 as shown. The standards of the two outer blades are likewise supported by rods 25 fitted with turnbuckles 26. These rods 19and 25 take'up a great deal of the strain when the device is in use and consequently relieve the bolts 8 and 11.

It may now be readily seen that by loosen- 7 ing the set screw 18 the lifting blades may be adjusted laterally as desired to secure desired spacing of the blades of each pair, or to secure desired spacing of the several pairs mounted on the same bars 3-4. By loosening bolts 11 and operating turnbuckles 2426 the blades may be adjusted about their pivotal points 8. When the adjustment desired is secured the bolts 11 are again tightened.

While the structure may be mounted upon a specially built framework, one great advantage that it may be quickly mounted upon the framework of other implements. It is economical to manufacture, simple in form,-const1a1ction and operation, and highly eflicient, in practical application,

Furthermore, this construction enables one to operate upon two rows of beets at the same time, thestandardsofthetWo connected center blades having less curvature than the tWo outer blades and giving a fixed spacing corresponding :to :the standard spacing o1 the beet rows.

:It is to be understood, :of course, "that Wl1ll'-'I"l12LV6 herein shown and described "one specific embodiment of the invention, changes in iform, construction and method of operation may be made Within the scope of the appended claim.

I claim A beet lifter comprising in combination with a carriage frame, a pair of parallelly arranged bars spaced a distance apart laterally'and vei'ticallyfmeans for securing said bars in rigid relation to each other, means for pivotally mounting said last. mentioned means 'onsaid carriage frame to move in a vertical plane, means for adjusting said pivotally mounted *means, and a pair of beet lifting elements adjustably mounted beit-iireen said spaced lpara'llelly arranged 'b'ars.
